Doomsday Bunker Upgrade

The small harvester looks like a walk-behind weeder, although from structure to principle, there is almost no difference between the two, and even the walk-behind weeder can be modified into a harvester with a little modification. , But there are still some differences between the two.

In particular, Chen Xin is a mini combine harvester with threshing function, which is quite different in shape.

The principle of both is to use the engine to drive the blade to cut the stalks of the plant, but the weeder needs to adjust the height of the blade according to the needs to avoid cutting the lawn too bald, and the harvester needs to appropriately increase the blade and add The upper guide vanes are used to better cut the crop stems.

When using it, only the engine is needed, and then aim at the crop to be harvested, and then push forward at a constant speed.

This kind of small harvester has rollers and crawlers at the bottom. As long as the handle is held firmly, the crop can be harvested smoothly without the possibility of running crooked or running off the track.

Compared with manual harvesting, mechanical harvesting has considerable advantages in terms of efficiency and cost. After all, people will be tired, but machines will not.

Chen Xin's one is too small, so it is a hand-held type. A slightly larger one can even have a seat on it. It can be fully seated and can be said to be quite comfortable.

So when the upland rice in the field matured, Chen Xin had already filled the small harvester with oil, and was ready to harvest after starting.

"Zizzi! Zizzi!" With the operation of the engine, Chen Xin only needs to push the machine forward, and the sharp blade will quickly cut the rice stalks.

In addition, Chen Xin uses an integrated combine harvester, and the cut rice will be directly crushed and threshed under the action of the machine, and turned into hulled grains in bags, leaving only the rice after the threshing is completed on the ground. stalk.

Compared with traditional manual harvesting, you need to hold the rice stalks with your hands, and then cut the rice stalks with a sickle. This is really much simpler.

After all, what is harvested manually is the ears of rice that are attached to the stalks, and they need to be threshed again. Even with the help of a thresher, this is a very heavy work.

But there is no such trouble with a combine harvester, and the cut rice can be processed directly into hulled grains.

So when a ridge of rice was cut and the grains were all in the bag hanging next to the harvester, Chen Xin couldn't help whistling cheerfully.

He originally thought that harvesting rice would be a tiring job before changing to a small agricultural machine, but he didn't expect it would be so easy after using the machine.

This naturally greatly strengthened his enthusiasm, pushing the harvester to continue harvesting quickly, striving to cut all his rice fields within an hour.

The part that Chen Xin wants to harvest is not too much. In a total of only 200 square meters, there are still 50 square meters where carrots are grown, so what he wants to harvest is only 150 square meters of rice fields.

However, although the small harvester makes the harvesting work very easy, Chen Xin still needs to lower his head, as if he is lying on the handrail of the harvester with his back hunched, because the height of the hydroponic planting plate above his head is really low. Caused him to be unable to straighten up.

Of course, this is much easier and more comfortable than bending over and cutting rice.

Therefore, without spending too much time, Chen Xin cut all the one hundred and fifty square meters of dry rice.

The cut rice was also threshed by the combine harvester and packed in a bag on the machine.

The bag was not sealed, but it was already full. Chen Xin tried to reach out to lift it, but it was so heavy that he could barely lift it.

One hundred and fifty square meters of upland rice is filled with three huge sacks after harvest, and the average bag is about 70 or 80 jin.

Of course, this is the grain that has not been hulled, and it needs to be dried and stored for a long time.

Although it is not impossible to hull directly into new rice, the rice grains are likely to break because there is still a lot of moisture.

If this process was in the past, it would not be very troublesome. Just find a flat ground and spread the grains to dry. As long as it is a flat concrete ground, it can be used to dry rice.

Chen Xin had even seen farmers drying rice on the road before, so this work was mainly based on the weather, not on the site.

But now the most convenient and direct heat source is gone, and it is impossible to put the millet out in the snow. The only place where sun-tanning is possible is inside the refuge.

Only considering the lack of space inside the shelter, Chen Xin decided to use mechanical drying to remove moisture from the grains instead of natural air drying.

Although the taste of mechanically dried grains will become worse, it is better than leaving these rice grains in this way to cause mildew or germination.

As for how to carry out mechanical drying, the continuous heat source of ground source heat pump is not difficult to solve.

Whether it is roasting with a tray or blowing hot air with a blower, it is a way to remove moisture from the rice.

Efforts to move the three sacks out of the planting greenhouse~www.ltnovel.com~ Chen Xin did not put the three bags of rice in the storage room, but just opened the pockets in the public space.

Before the dryer was built, the rice could not be stored in the warehouse, so it is the correct way to open it first.

As for making the dryer, Chen Xin scratched his head a little. He has neither done it nor seen it before.

Even with the information in the computer, no relevant pictures or text descriptions were found, which made Chen Xin very worried.

What should I do with this thing? Is it really a big tray to bake?

However, Chen Xin only dismissed this idea after passing it in his mind, because it was a bit unreliable. After all, if the temperature is low, it is better to say that the temperature is too low. If the temperature is too high, just roast the rice. , That would be embarrassing.

However, under contemplation, Chen Xin remembered the clothes dryer he had used and the household dryer his mother had used before.

The principle of both is to dry the damp items with relatively high temperature air in a relatively closed space to remove moisture.

Can you make something similar and use it to dehydrate the grains?

Chen Xin thought about it and felt that this method should be feasible, but before doing it, he still planned to draw a drawing to study it.

After all, I haven't practiced it before. If you start it directly, it will be a small thing if something is broken, and the system will be used to disassemble the recycled materials. But if the grain is destroyed, the loss will be at least one-third of the harvest this year.

So for the sake of prudence, Chen Xin decided to draw the drawings of the equipment first, and then carefully study the feasibility.
